PACKAGING DEVICE.

Specification of Letters Patent. Patented Dec; 27, 1921- Application fled A r-n20, 1921. Serial Io. 462,885.

Be it known that I, MATHIAS B. BECKER, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement. in Packa 'ng Devices, of which t e following is a fuTl, clear, concise, and exact description, reference being had to the accompanying drawings, forming a art of this specification.

y invention relates to packaging devices and more particularly to packaging devices consisting of straps and buckles.

My invention finds great utility when used for packa "ng asphalt shingles and the like. Asp alt sgingles, that is, shingles which are made of material consistin chiefi of asphalt, are comparatively plia le, an "arc susceptible to in urywhen bound in bundles with twine orwn'e. The use of twine or wire for this purpose generally results in a substantial percenta of mutilated shingles, moreover the use 0 twine or wire is unde sirable because shin les of the kind mentioned dry out and s rink, thereby causing the twine or wire to become slack.

The objects of m invention are:

To provide a pee ging device with which a number of articles can be quickly bound together without attendant injury to the articles.

To Iprovide a packaging device which is capab e of minute read ustments without removing it from its age, and

To provide a device of the class described comprising a belt of woven material, and a buckle, the buckle ha means whereby it posltion about the packcan be detachably secure to the belt.

These and other objects of my invention will be more clearly pointed out as the following description progresses, reference being had to the accompanying drawings, wherein Figure 1 is a pprspective view of a ackage of asphalt s in lee, the shingles ing bound together by t e improved packaging device of my invention;

Fi 2 is a perspective view of a buckle w hic forms a part of the packaging device;

Fig. 3 is an end elevation of the buckle, the buckle being shown in operative association with a suitable strap and Fig. 4 is a rear elevation of the buckle, the

bucklebeing stra Slmilar characters of reference indicate similar parts throughout the several views.

In Fig. 1, I have illustrated a bundle of asphalt shingles which are designated by the reference character 10. The shingles 10 are piled upon each other in any desired quantity, as shown. A strap 11 is shown disposed about the shingles 10, its ends being secured by a buckle 12. The strap 11 and buckle 12 embody the novel features of my invention. The strap 11 is made preferably of coarsely woven material, and is of sufilcient width to prevent it from cutting into the shingles. The flexibility of a strap of this character permits it to be drawn tightly and shown engaging the ends of the snugl about a bundle, thereby securely holdin t e contents of the bundle together.

he buckle 12 preferably consists of a single piece of wire, the wire being bent to form an open loop 13, as shown in Figs. 2, 3, and 4. The loop has an end bar 14, side members 15-15 and tangs 16-16, each of the tangs 16-16 being joined to a side member 15 by a portion 17 of the wire. The tangs are pointed as at 18-18. The tangs 16-16 are disposed to lie across the loop 13, but are also bent away from the plane in which the loop is disposed, thus allowing suflicient clearance between the sharpened ends 18-18 of the tangs and the bar 14"., to permit the insertion of the strap 11 into the buckle. However, the space so provided for the insertion of the strap 11 is made small enough to cause the strap to engage the sharpened ends 18-18 of the tangs 16-16 when an attempt is made to Withdraw the strap from the buckle without carefully guiding it by the sharpened ends 18-18.

The strap 11 being formed of coarsely woven material, it will be understood that the tangs 16-16 may pierce and secure the strap to the buckle, the tangs entering into the interstices between the Warp and weft.

For convenience, the two ends of the strap 11 will be designated by the reference characters 20 and 21, the two ends of the strap being interchangeable. In the drawings, the end 20 has been shown impaled upon the tangs 16-16 and drawn down upon the tan so as to rest a ainst the ortions 17-17 of the buckle. he strap is isposed around the shingles and its other end 21 is also secu ed t h m g 16-1 It is apparent that the strap may be tight ened about the shingles by simply pulling upon the end 21, the tangs 16-16 being so positioned that they will readily pierce the strap when the operator ceases to pull upon it. The tension of the strap will draw it down upon the tangs. This structure per- Inits the strap to be tightened at any time to compensate for shrinkage of the shingles. The package may be handled by the strap end 21, and when it is carried by this ench the Weight of the 'paokage will cause the belt to tighten itself about the package.

'In the operation of the device, either end of the strap may be first detachably secured upon the tangs 16-16 of the buckle, and the strap disposed around the articles to be bound. The other-end of the strap is drawn through the buckle until the strap is suitieiently tightened about the package. This end of the strap is then guided upon the tangs 1616,the tension of the strap drawing it down'uponthe tangs as hereinbefore described.

What-I claim is:

Adevice of the class described comprising a belt, a single piece of'wire pointed at both of its ends andbent to provide a cross bar (14),-a-pair of sidebars (15-15) which my name this are parallel to each other and disposed at right angles to the aforesaid cross bar (1d), a pair of shorter cross bars (l7-17) which are disposed in the same plane with said side bars (15-45) and said first mentioned cross bar (14) and in a straight line at right :v

closely adjacent to said first mentioned cross bar (1 1), one end of said belt being impaled upon said tangs and lying against the atom said shorter cross bars (l717), the other end of the belt extending under said first mentioned cross bar (1 1) from the side thereof opposite said tangs and being also impaled upon said tangs.

In witness whereof, I hereunto subscribe 14th day of April, 1921. MATHIAS B. BECKER. Witnesses:
